TIE-PLATE;

To wZZ whom/it may concern Be it known that I, EnwAnnL. FLINN, a citizenof the United States, residing at For estville, in the countyof Hamiltonand State Fig. 1; and Fig. 4, a perspective view, on an enlarged scale,of the tie-plate turned upside down.

The tie-plate proper is in the form of a fiat plate Ayhaving a shoulderB overlap ing one edge of the flange c of rail C. On t 1e other side thetie-plate is provided with o enings CL, located a ong the edge of therai -fiange and through which spikes D are driven into tie d, with theirheads engaging the gods of the rail-flange. Outside. of shoulder B theedge of the plate is provided with notches a, through which spikes E aredriven, with their heads engaging the plate. The shoulder B is intendedto be placed on the outside of the rail, in which case the outsidefastening of the tie-plate is made by spikes E, which are driven fortheir [1111 available length, and thus afford a very secure fastening atthe outside or" the tieplate, where there is the greatest strain. On itsbottom the late is provided with blades or ribs F and ada ted to bepressed into the tie d. The outsi e blades F are made slightly widerthan the inside blades and notches f and g,'formed in both sets ofblades, the notches preferably extending partly through the blades,thereby leaving a strengthening-rib for the plate throughout the lengthof each blade.

tion the blades are pointed at their outer ends to form entering edges.Then they are gradually thickened to points f and 9, then they arenarrowed to points f and g and then they are thickened or'fiaredconsiderably at their juncture with the plate A.

In use it is intended that the tie-plates be placed upon the ties withrails in position and the blades pressed into the ties by passingrolling-stock over them." Then the plates are further secured by thespikes D and E. When the blades are pressed into the ties, portions ofwood of the ties are forced and compressed into notches f and g andserve to securely lock the plate against endwise movement. expands intothe concavities in the neck of the blade, and thus forms ananchoring-lock against removal of the plate. The notches g in blades Gare staggered'or placed out of line with notches f in blades F, so thatthere shall be no cross-section of the plate not reinforced andstiffened by blades F or G.

I claim as my invention- 1. The combinationnf a tie-plate; anoverlapping shoulder at one side adapted to engage the rail-flange;holes along the edge of the rail-flange at the other side adapted toreceive spikes; notches in the edge of the plate outside the shoulderadapted to receive spikes, and notched blades upon the bottom of theplate adapted to enter the tie, substantially as specified.

As the blades enter the tie the wood 2. The combination of tie-plate A;open- I alinement with each other, substantially as specified.
